Turbulence is one of the last remaining challenges in the simulation of fluid flows. Although RANS (Reynolds-Averaged Navier Stokes) turbulence models are still very widely used, these approaches are being slowly supplanted by Large Eddy Simulation (LES).

With tornado season fast approaching or already underway in vulnerable states throughout the U.S., new supercomputer simulations are giving meteorologists unprecedented insight into the structure of monstrous thunderstorms and tornadoes. One such recent simulation recreates a tornado-producing supercell thunderstorm that left a path of destruction over the central Great Plains in 2011.

Metal casting simulations are among the most challenging of CFD simulations due to the extreme complexity of flow and physics that occur during fill, solidification and cooling stages of any casting process.

Flow Science invites you to join us for a technical webinar on May 18 that will present a broad review of FLOW-3D Cast's modeling capabilities, including detailed examples taken from many casting applications: LPDC, full HPDC cycles, centrifugal casting, lost foam, sand casting, continuous casting, tilt pour, and gravity pour in permanent molds.

A simulation based characterization workflow allows you
to characterize complex geometries for use within a
FloMASTER simulation. Join this web seminar to learn how FloEFD can be used to characterize complex multi-arm geometries for use in FloMASTER thermos-fluids simulations.
